Im lookin at a set of headers on ebay, i asked if they will fit a 70 chevelle, he said he thinks so, his friend took them off a 69 firebird. they are big block headers. Is he full of it to sell them or what? thanks

Assuming the Firebird had a BBC... '67 thru '69 "F" body big block FULL length headers will NOT fit a '68 thru '72 Chevelle.
